Brush Maker Optimizer erases white color. If it doesn't completely erase the background of the image, then try again until you only see the contours of the sprite itself.
Character sprites
Added in three black and white characters to the misc brushes menu. Man, woman and kid.
One New Brush Uploaded
There's one new brush in Shadowforge that I call the hairball. I hope you'll have fun with it.
Shadowforge 5.1.5
Fixed convex polygon (ALT + I, draw, ALT + I again then ALT + X). Only works on colored parts.
Made the lasso polygon tool do a sort of convex polygon when ctrl is held down while drawing with the lasso.
Shadowforge 5.1
There is a new icon on the left menu which when you click on it, it replaces the color on your chosen layer with the color you picked on the palette. Flat colors only.
